- initial working version of sybase, with modifications to the transactional

model to accomodate Sybase's default mode of "no ddl in transactions".
- identity insert not working yet.  it seems the default here might be the
opposite of that of MSSQL.
- reflection will be a full rewrite
- default DBAPI is python-sybase, well documented and nicely DBAPI compliant
except for the bind parameter situation, where we have a straightforward workaround
- full Sybase docs at: http://infocenter.sybase.com/help/index.jsp?topic=/com.sybase.help.ase_15.0/title.htm
